COMMENTS ON TROUBLE SYMPTOM

When the rear fog lamps do not illuminate normally, 
the mentioned input signal circuit(s) or ETACS-ECU 
may be defective.

PROBABLE CAUSES

• Malfunction of column switch

• Malfunction of the ETACS-ECU

• Damaged harness wires and connectors

DIAGNOSIS PROCEDURE

STEP 1. ETACS-ECU coding data check
(1) Operate the M.U.T.-III to read the ETACS-ECU 

option coding information (Refer to GROUP 00 

− 

Coding List ).

(2) Check that the "Rear fog lamp" is set to 

"Present."

Q: Is the check result normal?

YES : 

Go to Step 2.

NO : 

Operate the M.U.T.-III to set the option 
coding "Rear fog lamp" to "Present," and 
check the trouble symptom.

STEP 2. Check the operation of the position 
lamps and the headlamps.
Check that the position lamps and the headlamps 
illuminate normally.

Q: Is the check result normal?

YES : 

Go to Step 3.

NO : 

Check the position lamps and the 
headlamps (Refer to trouble symptom chart 

P.54A-96

).

STEP 3. M.U.T.-III diagnosis code
Check if diagnosis code is set to the ETACS-ECU.

Q: Is the diagnosis code set?

YES : 

Troubleshoot the ETACS-ECU. Refer to 

P.54A-281

.

NO : 

Go to Step 4.

STEP 4. M.U.T.-III data list
Use the ETACS-ECU service data to check the sig-
nal related to the operation of rear fog lamp function.

Fog lamp ON

ON

Turn the fog lamp switch to ON.

OK: Normal condition is displayed.

Q: Is the check result normal?

YES : 

Go to Step 5.

NO : 

Troubleshoot the ETACS-ECU. Refer to 
Inspection Procedure 11 "The column 
switch signal is not received" 

P.54A-321

.

STEP 5. Check the bulb of the rear fog lamp
Check the bulb of the defective lamp.

Q: Is the check result normal?

YES : 

Go to Step 6.

NO : 

Replace the bulb of the defective lamp.

STEP 6. Resistance measurement at the rear fog 
lamp connector (earth terminal).
(1) Disconnect the connector, and measure at the 

wiring harness side.

(2) Measure the resistance between the rear fog 

lamp connector (earth terminal) and body earth.

OK: Continuity exists (2 

Ω or less)

Q: Is the check result normal?

YES : 

Go to Step 8.

NO : 

Go to Step 7.

STEP 7. Check of open circuit in earth line 
between the rear fog lamp connector and body 
earth.

Q: Is the check result normal?

YES : 

Go to Step 8.

NO : 

Repair the connector(s) or wiring harness.

STEP 8. Check of open circuit in RFOG line 
between the rear fog lamp connector and 
ETACS-ECU connector.

Q: Is the check result normal?

YES : 

Go to Step 9.

NO : 

Repair the connector(s) or wiring harness.

STEP 9. Retest the system
Check that the rear fog lamp illuminate normally.

Q: Is the check result normal?

YES : 

The trouble can be an intermittent 

malfunction (Refer to GROUP 00 

− How to 

use Troubleshooting/inspection Service 
Points 

− How to Cope with Intermittent 

Malfunction ).

NO : 

Replace the ETACS-ECU.

Inspection Procedure 5: The rear fog lamp indicator does not illuminate normally.

CAUTION

• Before replacing the ECU, ensure that the 

power supply circuit, the earth circuit and the 
communication circuit are normal.

• When the ETACS-ECU of vehicles without 

KOS is replaced, the encrypted code of the 
ignition key needs to be registered to the 
ETACS-ECU. (If the encrypted code is not reg-
istered, the engine cannot be started. Regis-
ter the encrypted code as described in 
Immobilizer System 

− How to Register Key ID 

P.54A-33

.)

COMMENTS ON TROUBLE SYMPTOM

If the rear fog lamp indicator does not illuminate nor-
mally, connector(s), wiring harness in the CAN bus 
lines, the ETACS-ECU or the combination meter may 
be defective.

PROBABLE CAUSES

• Malfunction of the ETACS-ECU

• Malfunction of the combination meter

• Damaged harness wires and connectors

DIAGNOSIS PROCEDURE

STEP 1. Check the rear fog lamp
When the rear fog lamp switch is operated, check 
that the rear fog lamps illuminate/go off normally.

Q: Is the check result normal?

YES : 

Go to Step 2.

NO : 

First, repair the rear fog lamp (Refer to 
trouble symptom chart 

P.54A-149

).

STEP 2. M.U.T.-III CAN bus diagnostics
Use the M.U.T.-III to diagnose the CAN bus lines.

Q: Is the check result normal?

YES : 

Go to Step 3.

NO : 

Repair the CAN bus line (Refer to GROUP 
54C 

− Troubleshooting ).

STEP 3. M.U.T.-III diagnosis code
Check if diagnosis code is set to the ETACS-ECU.

Q: Is the diagnosis code set?

YES : 

Troubleshoot the ETACS-ECU. Refer to 

P.54A-281

.

NO : 

Go to Step 4.

STEP 4. M.U.T.-III other system special function
Using M.U.T.-III, select "Test" from the special func-
tion of the combination meter. Execute the following 
item to check the rear fog lamp indicator. (Refer to 
Combination Meter 

P.54A-64

)

• Item 5: Illumination (AUTO)

• Item 6: Indicator (AUTO)

Q: Is the check result normal?

YES : 

Go to Step 5.

NO : 

Troubleshoot the combination meter. Refer 
to
